SPECIFICATION forming part of Letters Patent No. 281,563, dated J'uly 17, 1883.

Application filed April 24, 1883. (N model.)

' To all whom it may concern:

- Be it-known that LNEWELL SANDERS, of Chattanooga, in the State of Tennessee, have. invented: a new and.

scription of the same.

My invention relates to evaporators, for sorghum and like juices, of the class of that shown in the patent of Van Slyke, No. 57,224, of August 14, 1866. In evaporators of that class the pan is divided by partitions into numerous divisions, which divisions are connected by pipes leading from holes in the bottom under the partitions. By means of these pipes the juice is caused to circulate, passing from divi-' sion to division, being drawn from the bottom through the pipe, whereby various well-known advantages are secured. Some disadvantages arise from the special construction of the pipes. They are difficult and expensive to make and to repair. They hold too much of the juice or sirup, and they are very inconvenient to clean. It has also been proposed to form the connection between the compartments or divisions by means of depressions formed in the edge of the bottom out of the material of the bottom itself. These openings could not practically be formed in any part of the bottom, but must be made at the edge, because of a liability to fracture the metaL. I have endeavored to obviate these objections, and to provide a passage from the compartments underneath the division-walls of the pan, at any desired point, by means of a cup separately formed out of any suitable metal, and soldered or otherwise secured to a hole directly under the division-wall; and in this the first part of my invention consists. The second part consists in forming the division-wall by a fold in the bottom itself, and by cutting out the extreme edges of that part of the bottom metal which is to be folded up and form the division by half of each hole; and the third part of my invention consists in turning up the parts thus'cut out, and riveting or soldering them to the division-Wall, in order to strengthen it.

The accompanying drawings show, in Figurel, a plan of part of the improvement. Fig.

2 is a section on line :0 00, Fig. 1. Fig. 3 is a v useful Improvement inv Evapo'rating-Pans;,and I do hereby declare that the following is a full, clear, and exact 'desection through a single cup on the line parallel with the partition and by the side of it. Fig. 4 represents the bottom as it is cut previous tothe formation of the partitions. Fig. 5 is a section on line 1) o of Fig. 1.

The bottom'is cut, as represented in Fig. 4, preferably for a circular cup. The two halves of the opening are cut at a distance from each other equal to twice the height of the partition. They are out upon half-circles y y, leavingtheir straight sides uncut and parallel to each other. The metal is then doubled upon itself upon the linezz, andthe' metal is then again bent on eachside'on the'lines o c, at right angles, so as'to leave'the' bottom 'parts, M M, in the same plane; This brings the pieces of the two half disks together and forms a round hole. One or both of the half-disks are then bent up, preferably on the same side, and are riveted or soldered tothe partition thus formed. This leaves the lower edge of the partition straight across the cavity of the cup, and forms a passage for the sap.

Though I have shown and described the bottom being formed with the openings, and then folded, it is not the preferred form, as in practice I intendto make the fold in the metal first, toj form the division wall orwalls, and thencut theopenings in any suitable manner alongside, thus always striking the correct position. The half-disks are then turned up in the manner before described. The cup is stamped, pressed, or formed, in any of the Ways well known to the art, out of suitable material,

and is soldered exactly to the hole, formed in the manner described. In this way the partitions are formed without much soldering, and are strengthened without any waste of metal at exactly the place where theyneed to be reenforcedthat is to say, over the cups.

The cups can be formed without straining the metal, and very cheaply, and can be lo cated in any desired place.

I do not claim the cups, broadly, as when formed out of the metal itself; but

What I do claim is- 1. In an evaporating-pan, a bottom having suitable openings cut therein, a cup soldered about the opening, and a division-wall extending over the cup, substantially as described.

2. The bottom of the evaporating-pan, in

combination with the division-wall formed out In testimony whereof I have signed my name of the bottom of the pan, said bottom being to this specification in the presence of; two subcut to form openings for a cup, substantially scribing witnesses. as described.
